MCP.Pizza Chef: LofiFren

PicoCalc lets you run MicroPython on a Raspberry Pi Pico 2W handheld device with a color display and keyboard. You can write, upload, and manage Python scripts using a local web dashboard or AI tools like Claude Desktop and Cursor. It includes games, music tools, a terminal, and SSH client. Setup involves flashing firmware and installing software, which requires some technical steps.

  • SD card script auto-discovery

Quick Start

1. Flash the Firmware

  1. Power off the PicoCalc and unplug USB.
  2. Hold BOOTSEL on the Pico 2W, then connect USB.
  3. A drive named RP2350 appears.
  4. Copy MicroPython/firmware/picocalc_micropython_pico2w.uf2 to that drive.
  5. The device reboots automatically.

2. Deploy Files to the Device

Option A: Dashboard (Recommended)

The easiest way -- a local web UI that handles everything:

python3 MicroPython/tools/dashboard.py

This opens a browser dashboard where you can:
